MEANS FOR FASTENING GLASS PANELS TO THEIR SUPPORTS.

Application filed June 27,

T 0 all 107mm may concern:

Be it known that I, BERNARD (I. Down, a citizen. of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Means for Fastening Glass Panels to Their Supports, of which the following is a specification.

This invention relates particularly to devices employed for fastening glass panels in the frames of typewriting machines. In the Royal standard typewriting machines the sides of the main frame are equipped with glass panels to exclude dirt and dust and through which some of the mechanism may be observed and which transmit'light to the interior of the machine so that some of the parts may be more readily seen from the outside of the machine. In the Royal machine these panels are held in place in the inside of the frame by metal clips arranged inside the machine frame. In order to detach these clips and withdraw the panels it has been necessary to work from the inside of the machine and when the machine is attached to a desk, table or other support, to detach it therefrom and turn. the machine over or part way over in order to obtain access to the clips and the panels.

According to my invention I have provided means whereby the panel may he applied to the machine frame from the outside and may be in like manner detached. therefrom.

In carrying out my invention, each glass panel is surrounded by a metal frame provided with devices for holding the panel securely in the frame and. with tongues which are so formed. as to engage portions of the machine frame properly formed to receive them.

In the accompanying drawings Figure 1 is a side elevation of a portion of the frame of a Royal typewriting machine, with my improvements applied.

Figure 2 is a view, on an enlarged scale, and showing in perspective the glass panels and the manner of attaching them to the machine frame.

Figure 3 shows a cross section on the line 33 of Figure 1.

Figure 4t shows a vertical section on the line ll of Figure 1.

Each side frame of the machine is formed with openings A and B, and the frame is 1922. Serial N0. 571,220.

equipped with cushioning feet G whereby it is held some distance above the desk, table or support on which the machine is placed.

I have shown two openings in the side frame, a large one and a small one, as such openings are generally made in the frame of the Royal machine, but only one such opening need be used. Each opening is formed to receive a glass panel D or D. The panel I) has beveled edges and is surrounded by a metal frame E, having tongues e which secure the frame to the panel, and retaining tongues F and springs G by means of which the panel is attached to the machine frame. The opening A is surrounded by a ledge it having recesses a to receive the tongues F and recesses 01. to receive the tongues G. The ledge is set back from the outside of the frame and when the framed panel is applied it is seated on the ledge with the tongues F and G extending through the recesses a and (A The tongues F are in the form of hooks, while the tongues G have bent portions 9' which engage the inside of the frame in the manner indicated in Fig. 4. The panel D may be place-d in position in the manner indicated in Fig. 4;. The tongues l. are first passed through the recesses a, the panel be-- ing inclined. as shown, and then the upper part of the panel may be moved into the opening in such manner that the portions 9 of the tongues G- will engage the frame. \Vhen the tongues are thus engaged the panel is held in an upright position in the opening A, with sufficient security to prcvent it moving out of place until. designedly withdrawn. When desired the panel may be removed. The hand of the operator or repairer may be placed under the machine and by a slight pressure on the inside of the panel it may be detached. The panel D is in like manner surrounded by a metal frame E provided with tongues F and G, and the opening B is formed similarly to the opening A, the only practical difference being that it is smaller and the recesses a and a are formed at the sides of the openings instead of at top and bottom and the tongues F and G are arranged on the sides of the frame E instead of at the top or bottom thereof. The panel D may be connected with the machine in an obvious way and may be withdrawn therefrom in the same manner that the panel D is withdrawn.

While I. have shown the invention applied to beveled glass panels, especially intended for attachment to the frame of a typewriting machine the same invention may be ap-- plied to panels of other kinds mounted on other objects.

I claim as my invention:

1. The combination with a glass panel of a metal frame which surrounds the same and fits over one margin of one face of the panel, said frame having tongues which may be bent to engage the other face, and also having hooksand resilient tongues for connecting the same to a support by direct pressure alone.

2. The combination with a beveled glass panel of a metal frame which surrounds the same and fits over the margin of the beveled face, said frame having tongues bent over the other face to secure the panel and frame together, and. also having other tongues in the form of hooks and resilient bent tongues for connecting the frame to a support by direct pressure alone.

' 3; The combination with a machine frame having an opening in its side surrounded by a ledge provided with openings to receive fastening devices, of a beveled glass panel, a frame surrounding the same and having devices for securing it to the frame andtongues which pass through the openings in the ledge and automatically assume rctaining. position.

4;. The combination with a machine frame having an opening in its side surrounded by a ledge provided with openings extending therethrongh to receive fastening devices, of a beveled glass panel, anda frame surrounding. the same and having. tongues bent around the edge of the panel and turned inwardly behind the frame to hold the panel and frame together, said frame also havwhereby the frame and panel'may be moved into position by direct pressurealone.

5. The combination with a machine frame having an opening in its side surrounded by a ledge provided with openings extending therethrough to'receive fastening devices, of a beveled glass panel, and a frame which surrounds the same and has tongues bent around the edge of the panel and turned in.- wardly behind the frame to hold the frame and panel together, said frame also having hooks which extend through some of the openings in the ledge and engage the inner side of the machine frame, and tongues extending through other openings in t'h'eledge and automatically moving to engaging positionagainst the inner side of the machine frame.

6. The combination with a machine frame having an opening in its side surrounded'by a ledge provided with top and bottom openings therethrough to receive fastening devices, of a beveledglass panel, and a frame which surrounds the same and has tongues bent around the edge of the panel and turned inwardly behind the frame to hold the frame and panel together, said frame having hooks on its bottom which extend through the. bottom openings in the ledge and engage theinside of the machine frame,

and also having resilient tongues on its top which extend through the top openings in the ledge and automatically spring to position to engage the inside of the machine frame, whereby the panel and frame may be placed in position by direct pressure alone. In testimony whereof, I. have hereunto subscribed my name. V
